(LUT): In computer graphics, the color options in a graphics system, arranged by an index number. Also known as a color map. The lookup table may be allocated either by hardware or by software.
A resource in an aspect template that parses attribute values into properties and properties into attribute values. A lookup table contains an entry for each type of attribute value to be translated into and from properties.
An array of values from which functions corresponding to a given argument can be obtained. Menu
A database table used to map one or more input values to one or more output values.
In XIL applications, lookup tables are used for general image modification. Each entry in an XIL lookup table contains an index--a value that may appear in the source image--and a value or set of values to be written to the destination image. For each pixel in the source, a table-lookup function finds the pixel's value on the index side of the table and then writes the output value or values for that entry to the corresponding pixel in the destination.
Supports multiple merge text options for a lookup table.
an imaginary table in memory where you look up the answers to certain mathematical equations instead of recalculating them each time
a table that contains key values
A table that OCR for AnyDoc accesses to validate specific data residing on a processed document. For example, OCR for AnyDoc can access a P.O. number table to validate the vendor associated with the P.O. number on an invoice.
Reference table containing key attribute values which can be linked or related to data usually collected at a specific location.
is a table that stores correspondence codes (or tags) and their meaning. It is often a data file used by a program to get further information about a particular item. For example, HardDrake uses such a table to know what a manufacturer's product code means. This is one line from the table, giving information about item CTL0001 CTL0001 sound sb Creative Labs SB16 \ HAS_OPL3|HAS_MPU401|HAS_DMA16|HAS_JOYSTICK
1. A special tabular data file containing additional attributes for features stored in an associated feature attribute table. The table can be an external attribute table or an INFO table that describes coverage features. 2. A special lookup table in which numeric item values are classified into categories. For example, well depth can be recorded explicitly in the feature attribute table, but displayed and used as a set of classes, such as 0 to 250 feet, 251 to 500 feet, and so on. An INFO lookup table contains at least two items: the relate item and an item named either SYMBOL or LABEL.
A Tivoli Decision Support for OS/390 DB2 table that contains grouping, translation, or substitution information.
Database table that assigns display parameters to each value in a field to generate thematic maps. A list of values that are correlated to a range of other values. For example, according to a soil type name, reference to this table can identify the corresponding compressive strength, percolation, and erosion potential rating. A file that correlates a user defined ID number permanently assigned to a spatial feature with machine readable ID numbe that is subject to occasional change.
(Abbreviated LUT.) A mapping of an integer value to another integer value. This is used in displaying images and represents a mapping of the pixel value in the image or picture to the value shown on the display device. See also color lookup table.
In computer science, a lookup table is a data structure, usually an array or associative array, used to replace a runtime computation with a simpler lookup operation. The speed gain can be significant, since retrieving a value from memory is often faster than undergoing an expensive computation.
